One of the hidden secrets of getting more acceleration from any car is its gearing. By shortening the gearing, the car will have more mechanical advantage for acceleration. It's the same idea as riding a bicycle and using the lower gears to get up steep hills.


Maruha has manufactured a whole range of final drive ratios for drivers with different needs. The bigger the final gear, the more acceleration you get but you sacrifice top speed. How often do you spend driving at top speed? Almost never so this is a trade off most people are willing to accept.


The final gears are offered in these ratios:
